**Answer:**

the 90% confidence interval is ( **48.684 , 51.316 **)

**Step-by-step explanation:**

Given that :

the sample size = 36

Sample Mean = 50

standard deviation = 4.80

The objective is to calculate a 90% confidence interval.

At 90% confidence interval ;

the level of significance = 1 - 0.9 = 0.1

The critical value for

= 1.645

The standard error S.E =

=

= 0.8

The Confidence interval level can be computed as:

For the lower limit :

=50 - 1.316

=** 48.684
**

For the upper limit :

=50 + 1.316

= **51.316
**

Thus, the 90% confidence interval is ( **48.684 , 51.316 **)
